"Application filed February 1,1907- Borlal Io. 865.282- I I i To allwhom 'it may cdncern: 8 is 'substantially parallel to the axis ofrotation of the Be it known that I, LEVI J. WING, a citizen of theUnited States of America, and a resident of East Orange,

county of Essex, State of New Jersey,.have invented 5 certain new anduseful Improvements in Turbine-Fans,

of which the following is'a specification.

The present invention relates generally to ians,'and has moreparticularly reference to a combined fan and turbine motor. 1

The chief object of the invention isto produce a structure combining afan, or air current producer, and a tur- 'bine motor of such a,character that the' exhaust steam from the turbine will mingle with theair' current produced by the fan, so that the combined air and steam maybe utilized for the purpose of a forced'draf t device for boilers, etc.I

Another object is to produce a combined structure'oithe character setforth, simple and inexpensive in'its' construction. l

construction, combination of parts and elements hereinafter set forth.

In the drawings the invention is embodied a concrete and preferred form,but changes of construction gitimate and intended scope of theinvention.

In the said drawings: Figure 1 is a perspective view of a combined fanand turbine embodying my invention. 2-is a detail view of a portion ofoneoi the vanes showing the, recessed portion and supporting shoulder.Fig. 3 is an edge view in section of one of the vanes showing thearrangement of the buckets and the steam nozzle. 4 is an enlarged detailview of the outer portion oi one of the vanes.

Siinilar characters of reference indicate corresponding in the differentviews; I 1 indicates a casing, of any suitable construction, withinwhich is mounted a plurality of vanes 2 on shaft 3 for producing orcreating a current of air in a direction parallel to the axis ofrotation oi the vanes. Each vane is provided at its periphery with arecessed portion 4 I and asupporting shoulder 5. Mounted upon these sup-1 portingshoulders within the recessed portion is a circumferentialbucketsupporting member 6 having the buckets]. These buckets are curvedin cross section and stand so that the plane of the impact surfacesstrued'accordingl y;

To this end the invention comprises the features of anangement of may ofcourse be made without departing from the le-' steam after striking thebuckets will then exhaust into' the casing and be by the fan. r

In place of steam, compressed air or any other impellin'g fluid may beused. The claims should be contaken up by the current oiair createdHWhatIclaimis:
